Study on the visualization function based on stroke rehabilitation mobile devices

In order to make the visualization function of stroke rehabilitation mobile devices more effective in assisting patients with health management, this paper explores the correlation between user needs and design elements as well as that between new products and market competitiveness using Quality Function Deployment (QFD). First of all, we collected 27 user needs based on the questionnaire surveys and KJ method. Then QFD is used to convert the six key user needs of the right to 16 design elements on visualization functions perspective, and use the results to guide the design development. Finally, the importance of design elements and market competitiveness was evaluated. The findings show that the application developed in this case has a certain advantage over the other three representative similar applications in terms of market competitiveness. Its core competitiveness based on visualization functions perspective which have met the user needs for a convenient personal health management, a clear medical center route navigation and a simple operation mode. It can be seen that the design and development of visualization functions of stroke rehabilitation mobile devices based on QFD decision-making is successful. The paper proposes that it be used as a reference for the future design and development of similar products.
